$10 - timer to count in .1 second increments help!!

elfarez · 10-23-2010, 07:58 AM

I need the timer on my app to count in .1 second increments and it currently only counts in one second increments and despite my efforts I cant do it, obviously I'm pretty unexperienced. Please help, first person to solve my issue will get $10 AUS (worth more then 10 US at the moment!) through paypal.

I have the time displayed as a label.

in .m

Quote:

- (IBAction)start{

myTicker = [NSTimer scheduledTimerWithTimeInterval: 1 target:self selector:@selector(showActivity) userInfo:nil repeats:YES];
stopButton.hidden = NO;

startButton.hidden = YES;
resetButton.hidden = YES;

}
- (IBAction)stop{
[myTicker invalidate];
}

}

- (void)showActivity{
int currentTime =[time.text intValue];
int newTime = currentTime + 1;
time.text = [NSString stringWithFormat:@"%d", newTime];

}

It all works for counting in seconds. I'm not experienced so could you please tell me how to fix this issue in a bit of detail.

Cheers

- (IBAction)start{

myTicker = [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(showActivity) userInfo:nil repeats:YES];
stopButton.hidden = NO;

startButton.hidden = YES;
resetButton.hidden = YES;

}

Sorry i should have been more clear. I want the timer to show the time increasing in .1 sec increments e.g. 0.1,0.2,0.3 ect.

Cheers

Please help.

Please help.

For the timeInterval in the code that iSDK gave you, use a variable...

Initialize it with...

Code:

float timeInterval;

timeInterval =0.1;

then increment it with...

Code:

timeInterval = timeInterval + 0.1;

myTicker = [NSTimer scheduledTimerWithTimeInterval:timeInterval target:self selector:@selector(showActivity) userInfo:nil repeats:YES];

That should work.

If you are offering payment, give it to iSDK. He deserves it.

Thanks

Sorry could you please tell me how to apply this code, I'm a beginner and have next to no experience. I'm just trying a few very basic projects to learn the basics of Xcode.
Cheers

I don't see anything posted so far that will do what you want, so here's something that will get you relatively close:

Code:

- (IBAction)start
{
    myTicker = [NSTimer scheduledTimerWithTimeInterval:0.1f target:self selector:@selector(showActivity) userInfo:nil repeats:YES];
    stopButton.hidden = NO;
    startButton.hidden = YES;
    resetButton.hidden = YES;
}

- (IBAction)stop
{
    [myTicker invalidate];
    myTicker = nil;
}

- (void)showActivity
{
    float currentTime = [time.text floatValue];
    float newTime = currentTime + 0.1f;
    time.text = [NSString stringWithFormat:@"%.1f", newTime];
}

Note that the technique used in this code does not provide the most accurate display possible, but it's simple and should probably do the trick for you.

    time.text = [NSString stringWithFormat:@"%.1f", newTime];

That's what he was asking?

Interesting as it seemed much too simple.

I interpreted his question to mean...have my repeating timer fire at 0.1, then 0.2, then 0.3 etc intervals... a math progression so to speak.

And all he wanted was a label display.

Coded of course.

Looks like Kalimba is owed the money.
